1* Texas Instruments wl1251 wireless lan controller
2
3The wl1251 chip can be connected via SPI or via SDIO. This
4document describes the binding for the SPI connected chip.
5
6Required properties:
7- compatible :        Should be "ti,wl1251"
8- reg :               Chip select address of device
9- spi-max-frequency : Maximum SPI clocking speed of device in Hz
10- interrupts :        Should contain interrupt line
11- interrupt-parent :  Should be the phandle for the interrupt controller
12                      that services interrupts for this device
13- vio-supply :        phandle to regulator providing VIO
14- ti,power-gpio :     GPIO connected to chip's PMEN pin
15
16Optional properties:
17- ti,wl1251-has-eeprom : boolean, the wl1251 has an eeprom connected, which
18                         provides configuration data (calibration, MAC, ...)
19- Please consult Documentation/devicetree/bindings/spi/spi-bus.txt
20  for optional SPI connection related properties,

24&spi1 {
25	wl1251@0 {
26		compatible = "ti,wl1251";
27
28		reg = <0>;
29		spi-max-frequency = <48000000>;
30		spi-cpol;
31		spi-cpha;
32
33		interrupt-parent = <&gpio2>;
34		interrupts = <10 IRQ_TYPE_NONE>; /* gpio line 42 */
35
36		vio-supply = <&vio>;
37		ti,power-gpio = <&gpio3 23 GPIO_ACTIVE_HIGH>; /* 87 */
38	};
